Subject: RE: Negotiated Rulemaking ‐ Distribution Transformers Teleconference

To Bruce Hirsch and the DOE WG:

I compliment Bruce for explaining the situation so clearly.   

I am writing this to request that the DOE to layout their payback calculation process in a step by step

basis so we can follow the math and follow the assumptions.  The DOE positions that the efficiency

levels have the various years of pay back goes against the calculations of ALL the utilities that CPS deals

with.  No utility has instructed that we optimize to lower the losses using loss evaluation factors at 50%

load which are required to create the lower losses suggested by the DOE for even loss level 1 which

calculates out to $17 to 20 dollars per watt when compared to the present DOE efficiency requirements.

I am surprised about the lack of concern about the cost per watt improvement that the other working

group members have shown when they keep insisting on the lower loss levels that cost $20 and even

$30 per watt to create.   

Claims that loss levels 3 and 4 can be economically produced using silicon core steel are not true using

the computer programs that belong to CPS.   

The Cooper Power Systems position is that if it is not economically justified, we will not support it.  We

expect that if the extremely high efficiency requirements are adopted, core steel will not be available

when needed and that the numbers of new transformers will decline dramatically as many  utilities

decide to rebuild rather than to purchase new transformers.  If this happens, the overall transformer

losses will likely go up rather than down.

Regards,
               Jerry Corkran

Steve,

I am disappointed with your approach to this assignment.  

It appears that negotiation to you is defined as agreeing with your position ‐‐‐ or calling it off. It is

unfortunate that you believe the American public, especially in these trying economic times, should be

expected to foot the (very large) bill for more efficient transformers when it is still not certain that there

is value in doing so. You have clung to one suspect calculation that indicates there may be a payback ‐‐‐ 

in the distant future ‐‐‐ and only if all the assumptions being made pan out. You choose to ignore the

costs, not yet factored in, on US jobs, US businesses and the reliability of supply of an item so

desperately needed for our economy to expand.  

This is not a “cut and dried” economic decision but is one that needs to be taken seriously for the major

impact it could have on the electric supply of the US and the financial position of the American public. If

DOE makes the final decision on this, I would expect them to do “due diligence” in considering all the

effects there decision would have on US businesses and the US economy.   

Let it be known that the Utility Industry has not pulled out of the negotiation process and will continue

to work with DOE to reach the right decision.  

Bruce.

Phil,

  

We're in the middle of negotiations and some of us have made clear that no or little change to the

standard is not acceptable as the DOE analysis justifies higher standards (higher levels are technically

feasible and cost‐effective on a life‐cycle cost basis).  The efficiency groups would rather leave the

decision to DOE than agree to subpar standards.  If you and other participants want to veto any

significant change in the standard, then we might as well save some time, break off negotiations and

just make our respective arguments to DOE.  Is that what you want to do?  If the answer is no, then let's

start talking about how to make higher standards acceptable rather than continue to make arguments

about why low standards are needed.  We're all busy and if we're going to make progress we need to

break new ground and not rehash old ground.

  

Steve

Hello Robert and all:

You must not have looked at Jerry Corkran’s message because he found the cost to be $17/watt, which

is pretty close to my number, where both Jerry and I have used M3 core steel to derive the cost curve.  

The fact is that the cost curve is very steep with M3 and quickly hits the brick wall.  

1.        I have checked Carlos Gaytan’s cost curves as well and he is finding about the same relationship

with M3.  
2.        I have checked Wes Patterson’s data as well and he is finding an M3 cost curve about the same as

mine.

3.        I have checked the OPS data with M3 as well and it too is very close to $20/watt.

a.       For example, for design line 1 they show an efficiency at 50% load of 99.08% which translates to

232 watts of loss and sells for $1,960.73.

b.      They show another M3 design with an efficiency of 99.26% which translates to 186 watts of loss

and sells for $2962.11.

c.       The change in selling price is $2,962.11‐$1,906.11 or +$1,001.38

d.      The change in watts is 232‐186 or ‐46 watts.

e.      The OPS $/watt is therefore, $1,001.38/46 watts or $21.77

f.        Hence we see that all data sources are pointing to cost per watt of ~$20 /watt saved to go from

the current mandatory standard to EL1.  I get $30/watt to go to EL2 and $53/watt to go to EL3

4.       The fact is that M3 is about out of gas and the DOE did a good job in the last rule making.

5.       The fact also is that a push to anything beyond present does not show economic value and I do not

support it.

6.       The fact also is that a push to higher efficiencies will kill the new transformer market and open up

the rebuild market, destroying jobs at the new transformer manufacturers and resulting in transformers

of lower efficiency which will cost energy and not save it.

Phil

Subject: Re: Negotiated Rulemaking ‐ Distribution Transformers Teleconference

Even if it were that high (and Mr. Hopkinson is the only one I've seen who has put the number anywhere

near that), the efficiency objective is saving Watt‐hours (energy) not Watts (the capacity to save energy)

. One Watt saved for 8,760 hours per year for 30 years is 262.8 kWh (not counting leap years). Even at

Mr. Hutchinson's $20, that's just over 7¢ / kWh. If Mr. Hutchinson will examine his electric bill, as he has

reported, he will see that even as high as 7¢ it's a good buy, and that assumes we put a ZERO value on

any environmental benefits (which is why DOE agreed to reconsider its 2007 MEPS in the first place.

Indeed, the cost of losses per Watt (roughly the A factors that OPS has been using) are no where near

the $20 claimed here. Moreover, as ABB and others have pointed out, the proper approach would have

been to minimize cost subject to efficiency, not A & B, which would have resulted in a lower, flatter

curve to the asymptote. ABB's actual market data ‐‐ physical transformers produced and delivered ‐‐ 

shows a competitive market for M3 transformers even at EL4 efficiency.  You can make all the

hypothetical claims you want to, gentlemen, the market is the real world.

That is also what my analysis and report said.  If you restrict to M3 then the cost of EL1 rises to about

To Mr. Parker and the DOE working group,

  

The reason for the request for the incremental cost of the losses is that the current DOE efficiency levels

can be obtained if the design is optimized at about $4 per core watt and $1 per winding watt at full

load.  At the DOE 50% kVA rating, this is the same as evaluating the losses or optimizing the design at

about $4 per total watts loss.   

  

The present DOE efficiency loss level results in transformer designs about like many utilities were

purchasing their transformers before 2007.   The utilities were purchasing the efficiency levels that were

justified based on the cost of losses.  A few utilities  were purchasing higher efficiency that the 2007

efficiency rules because of the calculated cost of energy being higher than the $4/$1 loss evaluation.   

  

What came up in the discussion last week was even for loss level 1, the incremental cost of losses was

about $17 per watt for the design checked, between the present DOE losses an efficiency level of DEL1.  

The added cost of $17 per watt is so much higher than the typical cost of the energy for the utilities,

that  it is very questionable that the DOE payback estimates are accurate.  A 3% interest rate may be a

factor in the payback calculations.

Thank you Richard. That clarification is helpful.

  

In the liquid‐filled meeting we were told that we would receive an analysis of incremental Watts saved

by DL for all ELs, as well as the incremental cost. When will that analysis be available? For many of us,

that analysis is the basis for additional, perhaps extensive analyses, so it should come with enough lead

time before any additional meetings or teleconferences to that we can give it the required

consideration. It would be most helpful if the incremental cost were provided separately for transformer

and installation, with any pole component of the installation identified.

  

For the MV Dry and LV Dry meetings, it would be most helpful if you would also circulate an agenda with

objectives, hopefully this week, so that we are able to prepare for those meetings.
